Why does benodryl not make me fall asleep. i feel my sneezing gets worse and all sweaty on my bed
For many people Benadryl -dypheniramine acts like a stimulant instead of a sleep medication. This is an allergic reaction, which means that any allergy medication with the ingredient of dypheniramine in it, will have the same effect. It also will increase ones cardiac effect and give dizziness or high blood pressure, even shortness of breath. Therefore you should not take it.
